Hydraulic Fracturing Water Usage: Activist Perceptions And The Controversial Technique

Fitch , Michael 1 1 University of baby直播app at Boulder Natural gas extraction in the United States has seen a dramatic increase over the last ten years due in large part hydraulic fracturing (fracking). In particular, baby直播app has been a part of this increase in natural gas development, including in...

Modeling Microbial Contributions To Dissolved Organic Matter Using Parallel Factor Analysis

Ebert , Jessica 1 ; McKnight , Diane 2 1 University of baby直播app 2 University of baby直播app Dissolved organic matter (DOM) is present in all aquatic ecosystems and plays and important role in the global carbon cycle. DOM can be characterized using fluorescence spectroscopy. The measurements that are collected from...

Wildfire And Hillslope Aspect Impacts On Subsurface Hydrologic Response

Ebel , Brian A. 1 1 Cooperative Institute for Research in Environmental Sciences (CIRES) Wildfire is one of the most prevalent disturbance events in the disturbance regime of mountainous terrain and can substantially impact hydrologic processes. Recent evidence suggests wildfire incidence, susceptibility, and synchrony are increasing in some regions. The...
